American lingerie model Caprice Bourret still hasn't told her two children about the circumstances of their unusual birth - because she isn't sure how to break the news.

The businesswoman, 46, welcomed Jax and Jett Bourret-Comfort into the world back in 2013, with one arriving three weeks after the other.

In an unusual twist, one of the boys was born via a surrogate mother - while the other was conceived naturally a month after the surrogate was impregnated.

Both of them are Caprice and her husband Ty Comfort's biological children, but the couple had already started the process of having a child through a 'gestational carrier' when Caprice realised she was pregnant.
